Let's define a function f(s) over a non-empty string s, which calculates the frequency of the smallest character in s. For example, if s = "dcce" then f(s) = 2 because the smallest character is "c" and its frequency is 2. Now, given st…

这是小川的第412次更新,第444篇原创 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第263题(顺位题号是1170).在一个非空字符串s上定义一个函数f(s),该函数计算s中最小字符的出现频率.例如,如果s ="dcce",则f(s)= 2,因为最小字符为"c",其频率为2. 现在,给定字符串数组queries和words,返回一个整数数组answer, 其中每个answer[i]是使得f(queries[i]) < f(W)的单词数量,其…

LintCode 58: Compare Strings 题目描述 比较两个字符串A和B,确定A中是否包含B中所有的字符.字符串A和B中的字符都是大写字母. 样例 给出A = "ABCD" B = "ACD",返回true 给出A = "ABCD" B = "AABC", 返回false Fri Mar 17 2017 思路 这道题跟前面一道『两个字符串是变位词』很相似,不同的只是在这题中两个字符串的长度可以不相等. 可以用同…
